Description

Technical Field

[0001] This utility model relates to the field of sealing strips, and in particular to a sealing strip. Background Technology

[0002] To ensure smooth opening and closing of doors or windows, a gap is usually left between the bottom of the door and the ground, or between the window and the window frame. However, due to the existence of gaps, wind, sand, dust, mosquitoes, insects, smoke, gas, noise, light, and rainwater can easily enter the room, polluting the indoor environment and affecting people's normal life and work. In particular, as modern people have increasingly higher requirements for their living standards, they need a quiet, comfortable, and clean home environment. The sealing effect of doors and windows is therefore of paramount importance. To address the above problems, the inventor has designed a high-sealing sealing strip. Utility Model Content

[0003] The main purpose of this invention is to address the problem that gaps at the bottom of doors and windows allow dust to easily enter and result in poor sound insulation.

[0004] To solve the above problems, this utility model proposes a sealing strip, including a sealing strip body and an adhesive backing layer. The sealing body is provided with an outer sealing body, and a protrusion is provided at the upper end of the outer sealing body. An adhesive backing layer is provided on the side of the outer sealing body, and the protrusion distance of the protrusion of the protrusion matches the thickness of the adhesive backing layer. A sealing foot is provided at the lower end of the outer sealing body, and an inner sealing body is provided on the other side of the sealing body. The inner sealing body has a shape that is a transition between a large arc and a small arc, forming a small waist shape. The distance between the inner sealing body and the outer sealing body first increases from the top, then gradually narrows in the middle, and then slowly increases and extends.

[0005] In one embodiment, an inner sealing foot is provided at the lower end of the inner sealing body, and several feet are provided between the sealing feet and the inner sealing foot, forming different height differences between the feet.

[0006] In one embodiment, a cavity is provided above the outer sealing body and the inner sealing body.

[0007] In one embodiment, a plurality of square cavities are formed between the outer sealing body and the inner sealing body, and the appearance of the square cavities varies with the distance between the outer sealing body and the inner sealing body.

[0008] In one embodiment, a spacer is provided between the square cavities.

[0009] In one embodiment, the cavity has a variety of shapes.

[0010] In one embodiment, the cavity is circular.

[0011] In one embodiment, a protective film is adhered to the outer side of the adhesive backing layer.

[0012] Beneficial effects: 1. The sealing strip of this utility model adopts a small waist arc transition design, which makes the sealing part rebound strongly, follow the force strongly, and have good toughness.

[0013] 2. The upper adhesive backing of the sealing strip of this utility model adopts a raised cover design to prevent dust from accumulating.

[0014] 3. The sealing strip of this utility model adopts multi-layer foot sealing. Its multi-layer foot will contact the floor, which can better fit the floor and achieve a multi-layer sealing effect, thereby making its sealing and sound insulation effect better. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To achieve the above-mentioned utility model objectives, such as Figure 1-3As shown, this utility model provides a sealing strip, which consists of a sealing strip body and an adhesive layer 7. A protective film is adhered to the outer side of the adhesive layer 7. The sealing body is provided with an outer sealing body 1. A protrusion 6 is provided at the upper end of the outer sealing body 1. The protrusion distance of the protrusion 6 matches the thickness of the adhesive layer 7. A sealing stop 4 is provided at the lower end of the outer sealing body 1. An inner sealing body 2 is provided on the other side of the sealing body. The inner sealing body 2 has a shape that transitions between a large arc and a small arc, forming a small waist shape. In terms of appearance, the distance between the inner sealing body 2 and the outer sealing body 1 first increases from the top, then gradually narrows at the middle end, and then slowly increases and extends. A sealing foot 41 is provided at the lower end of the inner sealing body 2. Several square cavities 3 are formed between the outer sealing body 1 and the inner sealing body 2. The appearance of the square cavities 3 varies with the distance between the outer sealing body 1 and the inner sealing body 2. A spacer 8 is provided between the square cavities 3. A cavity 5 is provided above the sealing body.
